WINDOW-VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 671,654, dated April 9,1901.

Application filed February 11, 1901. Serial No. 46,887. (No modem To allwhom, it may concern.-

Be it known that I, HERMANN W. Orro, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Window Ventilators, ofwhich the following is a specification.

This invention relates to improvements in window-ventilators, andespecially to that class of ventilators employed in art-glass windowssnch, for instance, as the windows of churches and other structures inwhich art glass orstained glass is employed; and it consists in certainpeculiarities of the construction, novel arrangement,and operation ofthe various parts thereof, as will be hereinafter more fully set forthand specifically claimed.

The objects of my inventionare to provide a window-ventilator whichshall be simple in construction, strong, and durable, and which may beso placed in the window as to be entirely surrounded by the stained orart glass or only partly surrounded thereby that is to say, it may beplaced in the central portion of the window or to one side or thetopthereof.

Another object is to construct the ventilator so that it willautomatically close and in such a manner that the glass may be readilyinserted in the frame and held in position so as not to rattle or becomeloose.

Still another object is to so construct the parts of the ventilator thata close and noise-' less joint between the frames of the ventilator willbe afforded.

Other objects and advantages will bedisclosed in the subjoineddescription.

In order to enable others skilled in the art to which my inventionpertains to make and use the same, I will now proceed to describe it,referring to the accompanying drawings, in which- Figure 1 is aperspective view of a portio of an art-glass window with my improvedventilator in position therein, showing it open for the purpose ofventilation. Fig. 2 is a perspective view of the frames of theventilator detached from the Window. Fig. 3 is an enlarged plansectional View taken on line 3 3 of Fig. 1 when the pivoted frame isclosed. Fig. 4 is a fragmental perspective view of a portion of theinner or pivoted frame. Fig. 5 is a vertical sectional view through'aportion of the two frames of the ventilator, taken on line 5 5 of Fig.2of the drawings when the pivoted frame is closed and looking in thedirection indicated by the arrows. Fig. 6 is an outer view of a likeportion of the outer frame of the ventilator, and Fig. 7 is aperspective view of a piece employed for securing the ends of the outerframe together.

Similar letters refer to like parts throughout the difierent views ofthe drawings.

A represents the outer or stationary frame of the ventilator and ispreferably formed of one piece bent to form a rectangular figure, as isshown in Figs. 1 and 2 of the drawings, but which may be formed into anysuitable shape. This frame is formed on its outer surface with a channela, the sides a of which are at right angles to its bottom (1, and is forthe purpose of receiving and retaining the glass B of the window, whichglass may be located entirely around the frame A or on one or more sidesthereof. The ends of the frame A are secured together by means of apiece A which is located in the channel a at the juncture of said endsand is provided with openings 1) forscrews b, which are preferablycountersunk on the innersurface of the frame and pass through the sameand engage the openings 1) in the piece A which is provided with acentral opening I) for the reception of a pivot or pin 0, which passesthrough one of the sides of the inner frame C and the outer frame, as isclearly shown in Figs. 2 and 5 of the drawings. The head of the pin 0 ispreferably countersunk in the inner surface of the pivoted or innerframe C, so as not to interfere with the glass 13', located in saidframe.

Secured to the front surface of the frame A by means of screws (:1 orotherwise is a plate or plates D, which extend inwardly from said frameand have interposed between it or them and the front surface of theframe A a piece of felt d or other suitable soft material, as shown inFig. 2 of the drawings. The plate D extends downwardly from just belowthe pivot-point of the inner frame C, and the back or rear surface ofthe frame A is provided with a plate or plates D, which extend upwardlyfrom just above the pivotpoi'nt of the frame C, and said plate or platesproject over the inner perimeter of the outer frame in a manner similarto the plate or plates D on the lower front portion of the outer frame.Interposed between the plate or plates D is a piece of felt d or othersuit able soft material. The frame 0 is made of a suit-able shape to (itclosely within the outer frame A and is pivotally secured by means ofthe pivots or pins 0 and-c therein, which are located above the middleof the sides of the inner frame, so that its lower portion will beheavier than its upper part, thus causing it to automatically close. Theframe 0 is formed with a channel e on its inner surface, the sides 6' ofwhich are at right angles to the bottom 6 of said channel, so as to forma rectan gular channel for the reception of the glass B,located withintheinner frame. The frame 0 is preferably made of two pieces 0 and(lithe ends of the pieces 0 being provided with countersunk openings fto receive screws passed through the openings 9 of the ends g of theportion 0 of the inner frame. The ends of the pieces 0 and O aremitered, as shown in Fig. 4 of the drawings, so as to fit closelytogether, and the ends 9' are bent so as to fit between the sides 6' ofthe channel in the portion 0, where they may be secured my means ofscrews located in the openings 9 and f therefor, as above stated. Theglass B within the inner frame, as well as the glass B located in thechannel of the outer frame, may be held in position by means of bars H,which extend from one side of the frame to the other and have their endsturned so as to be at right angles to their edges, as at h. (Shown inFig. 3 of the drawings.) By thus turning the ends of the bars Hit isapparent that the portions h may be placed between the surface of theglass and the sides of the channels of the inner and outer frames, thusfirmly holding the glass in position. When thus located, the bars Hwill. rest on the lead bars or cames h, which are employed in stained orart glass work.

To place the bars H in position, one of the turned ends thereof is firstplaced between the glass and one of the sides of the channel of theframe. When thus placed, the bar is held diagonally across the glass, asshown by dotted lines in Fig. 1 of the drawings, when its other end maybe placed between the glass and the side of the channel on the oppositeside of the frame, after which the bar may be pressed so as to be atright angles to the frame sides. The upper portion of the frame A may beprovided with a catch G to receive a spring-bolt G, of the ordinary orany preferred construction, which may be located on the upperportion ofthe inner frame.

In Fig. 1 of the drawings I have shown the outer frame entirelysurrounded by the glass B of the window; but it is apparent that saidframe may be located so as to be only partiallysurrounded thereby. InFig. 4 of the It is apparent that the outer frame of the ventilator maybe located in a wooden sash or so that a part of said frame or all of itmay be secured to said sash.

By using the piece A at the juncture of the ends of the outer frame itis evident that when said frame is secured to a wooden sash the screwstherefor may be removed, thus allowing the ends of the outer frame to besprung apart, so as to permit the pin 0 and the inner frame to beremoved.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In a window-ventilator, the combination with an outer frame having onits outer surface a channel to receive the glass of the window, of aplate secured to the front surface of the lower portion of the frame andanother plate secured to the rear upper portion of the frame, saidplates projecting over the inner perimeter of the frame, an inner framepivotally secured in the outer frame and having on its inner surface achannel to receive the edges of the glass for said frame, and a barhaving its ends located between the glass and sides of the channel,substantially as described.

2. In a window-ventilator, the combination with an outer frame having onits outer surface a rectangular channel to receive the glass of'thewindow, of a plate secured to the front lower surface of the frame, apiece of felt or other suitable soft material located between said plateand frame, another plate secured to the upper rear part of the frame, apiece of felt or soft material located between said plate and frame, thesaid plates and pieces of felt projecting over the inner perimeter ofthe frame, an inner frame pivotally secured in the outer frame andhaving on its inner surface a channel to receive the edges of the glassfor said frame, and a detachable portion, substantially as described.

3. In a window-ventilator, the combination with an outer frame having onits outer surface a channel to receive the glass of the windowof a piecedetachably uniting the ends of said frame, a plate secured to the lowerfront surface of the frame, a piece of felt or other suitable softmaterial located between said plate and frame, another plate secured tothe upper rear part of the frame, a piece of felt or soft materiallocated between said plate and frame, the said plates and pieces of feltprojecting over the inner perimeter of the frame, an inner framepivotally secured in the outer frame and having a detachable portion andprovided on its inner surface with a channel to receive the edges of theglass for said frame, substantially as described.
